This is the core of the problem. We've had your discussion about animal rights, we'll probably have it again. However This space isn't just yours, and other people want to do things with it that have nothing to do with your cause/concern. This makes them angry. Because you have been given your space to say what you want, and you aren't giving others the same courtesy. It's not what you're saying, it's when.regardless of context.
You didn't have to post here, you could have ignored me. What should I do? Apologise for making people angry for pointing out something they do? Thank you but I kindly decline your polite request to ask me to shut up. For as long as there's animal abuse, there will be people pointing it out. 
Isn't this the crux of everybody's argument when you start pushing your agenda when they make a comment related to animals and have no interest in debating you?You didn't have to post here, you could have ignored me.
I'm all ears regarding your or anyone's perspective. I'm yet to read one regarding animal rights.
I have every interest in debating. Do you see anyone raising any valid arguments for eating meat? Or do you see a bash the vegan fest, yet again? Also, what agenda is this that you mention?
